在linux系统下开启mycat，查看状态显示连接成功，但是NAVICAT工具进行连接mycat时就报如下错误：查看其错误日志文件：
# There is insufficient memory for the Java Runtime Environment to continue.
# Cannot create GC thread. Out of system resources.
# Possible reasons:

# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)

显示内存不足，我明明物理内存10G，运行内存1G，咋个不足，后来都增加一倍，错误直接解决。
